But ultimately, time on the poignant homefront is short lived as the story goes behind enemy lines in Caracas, the Andes mountains, and other exotic locales. It’s a space not often explored by modern shooters, and its mood is heightened by missions set in a besieged Santa Monica and the wasted remains of San Diego, to the tune of an excellent, somber score from David Buckley (The Town, Metal Gear Solid 4). The prelude establishes a harrowing vision of a United States homeland that's broken but not beaten – not quite Red Dawn, but not Fallout 3, either.
